Sleep Duration and All-Cause Mortality.

Abstract

Sleep, as a behavioural lifestyle factor, has so far received limited attention in medical risk assessment. Nonetheless, behavioural lifestyle factors can offer valuable insights into the health status of applicants. Health trackers enable the continuous recording of lifestyle factors such as physical activity and sleep patterns. Currently, there is a dearth of experience in incorporating such data when calculating premiums, as well as in understanding the correlation between continuously recorded lifestyle factors and mortality/morbidity. Hence, the literature was reviewed to examine the association between sleep duration and all-cause mortality to derive dose-response rates. Relative risks were calculated by pooling data from 10 selected studies comprising over 3 million study participants. The findings suggest that both short (<6 hours) and long sleep duration (>9 hours) are associated with an increased risk of all-cause mortality.
